How Germs Spread

Illnesses like the flu (influenza) and colds are caused by viruses that infect the nose, throat, and lungs. The flu and colds usually spread from person to person when an infected person coughs or sneezes.

Take care to:

Cover your mouth and nose when you sneeze or cough

Clean your hands often (with soap and water for 15 to 20 seconds rubbing your hands vigorously together to dislodge and remove germs)

Avoid touching your eyes, nose, or mouth

Stay home when you are sick, get plenty of rest, and check with a health care provider when severe symptoms are present
